VARIOUS OPERATING MODES
ON-BOARD LINKS: In order to quickly and easily change operating modes for
different applications, the meter has several on-board links. They are designed
to be easily opened (cut) or shorted (soldered).
Ensure thermocouple probes are isolated.
BACKLIGHTING
There are two ways to power the LED backlight. Either use a 5V (±10%) supply on LP+/LP- or use the internal meter 5V supply. If the internal
supply is used, the power supply voltage is limited to 7.5 - 15V D.C.
PANEL FITTING
- When connecting thermocouples, ensure that the wires are carefully cleaned and are connected directly to the module and not to some
With external backlight supply.
